Abstract
In recent years solar energy has been strongly promoted as a viable energy source. one of the most simplest and direct application of this energy is the conversion of solar radiation in to heat energy using a devices called sollar collectors [3].In order to enhance this conversion efficiency, important parameters that influence the system performances need to be evaluated. To achieve the state objectives, this paper investigates the effects of some meteorological variables (Wind Speed and Ambient Temperature) on the performance of parabolic trough collector. The results obtained show that wind speed is inversely proportional to the direct solar radiation and it has also shown that a maximum daily average wind speed of 1.39m/s was observed, when ambient temperature reach it lowest value. Furthermore, efficiency is highly correlated with wind speed and negatively correlated with ambient temperature.
